+        HTTP hyperlinks can have an extra <ulink url="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#ping">ping attribute</ulink> that sends a POST request to a different URL.
+        These HTTP pings are commonly used for tracking.
+        <ulink url="https://www.theregister.com/2019/04/06/apple_safari_changes/">Most browsers</ulink> send HTTP pings without informing the user
+        <ulink url="https://lists.w3.org/Archives/Public/public-html/2018May/0027.html">in any way</ulink>
+        (despite what The Register article says, current versions of FireFox also happily send HTTP pings).
+      </para>
+
+      <para>
+        Privacy Browser blocks all HTTP pings and presents a dialog informing the user every time the current tab attempts to send one.
+        Hopefully, as more people become aware of what HTTP pings are, web sites will become more embarrassed about using them.
+        This is a classic example of how those who wrote the HTTP specs do not have the best interests of internet users at heart. I would like the day to come where they are removed from the specs.
